CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a bypass continuation application of International Application No. PCT/CN2019/115519, filed on Nov. 5, 2019, which claims priority to Chinese Patent Application No. 201811433526.3, entitled “DRIFT METHOD AND APPARATUS FOR VIRTUAL VEHICLE IN VIRTUAL WORLD AND STORAGE MEDIUM” and filed with the National Intellectual Property Administration, PRC on Nov. 28, 2018, the disclosures of which are herein incorporated by reference in their entireties.

FIELD

The disclosure relates to the field of computer programs, and in particular, to a drift method and apparatus for a virtual vehicle in a virtual world and a storage medium.

BACKGROUND

Automobile racing games are a type of games popular with users. Currently, three-dimensional automobile racing games built in a three-dimensional virtual world are provided.

In the related art, a user generally uses a smartphone to run an automobile racing game application. In the running process, a user interface of the automobile racing game application is displayed on the smartphone. The user interface includes a traveling picture of a racing automobile traveling in a track in a virtual world, and a left direction key, a right direction key, and a drift control overlaying the traveling picture. If the user presses a direction key first, and then presses the drift control, the automobile racing game application controls, according to the press operation performed by the user, the racing automobile to enter a drift state.

In the related art, the user needs to simultaneously press a direction key and the drift control key in order to trigger a drift of the racing automobile and hold the drift state of the racing automobile, which requires cumbersome man-machine interaction operations, and is not conducive for the user to operate quickly in scenarios such as when the user is in a subway or a bus. Once an event occurs, such as a collision or a wobble occurring in the subway or the bus, the drift process of the racing automobile in the game application is likely to be accidentally interrupted.

DETAILED DESCRIPTION

To make the objectives, technical solutions, and advantages of the disclosure clearer, the following further describes implementations of the disclosure in detail with reference to the accompanying drawings.

The disclosure may be applied to the following scenarios.

An automobile racing game application refers to an application providing for one or more players to race in a same track. The application allows a racing automobile to enter a drift state during traveling. The drift state refers to a movement state in which a vehicle body slides through a turn in a case that a relatively large angle is generated between a vehicle head direction and a traveling direction. The application may be a standalone application or a network application. The application allows various competition manners such as individual racing, team racing, individual props, and team props. A racing automobile provided in the application may be at least one of a motorbike, a go-kart, a car, an electric vehicle, and a cartoon car.

A gunfight game application refers to an application providing for one or more players to perform a combat in an open game world. The application allows a game character to drive a military vehicle such as an infantry fighting vehicle, an armored personnel carrier, a scout car, a communication vehicle, a tracked vehicle, a tank, or an armored car in the open game world and control the military vehicle to enter a drift state while driving.

A sandbox game application refers to an open and creative application including one or more areas on a map and integrating various game elements such as action, shooting, fighting, and driving. The application allows a game character to drive various types of civilian cars in an open virtual world, and controls the cars to enter a drift state while driving.

A virtual vehicle in the related art is affected by, for example, a ground friction (and a wind resistance) in a virtual environment. When a drift operation performed by a user is canceled, the ground friction causes the virtual vehicle to decelerate rapidly, thereby canceling the drifting state, or even decelerating to zero.

Many current applications are developed based on smartphones or tablet computers. When a user uses a smartphone or a tablet computer to control a virtual vehicle on a transportation means, the virtual racing automobile is likely to be affected by factors such as a jolt and a collision in a real world, and therefore, the racing automobile cannot remain in a continuous drift state. The following embodiments are provided in the disclosure and may be used for resolving the foregoing technical problems.

FIG. 1 is a flowchart of a drift method for a virtual vehicle (or a method of controlling a drift state of a virtual vehicle) in a virtual world according to an example embodiment of the disclosure. This embodiment is described by using an example in which the method is applicable to a terminal running an application. The application is a program allowing a virtual vehicle to enter a drift state in a traveling process. The method includes operations 101-103:

Operation S101. Receive an operation start event corresponding to a target interaction control in a process in which a virtual vehicle in the virtual world is in a normal traveling state.

The application may be an automobile racing game application, an online game application, a mobile game application, or the like. The application is provided with a virtual world, and a virtual vehicle in the virtual world is provided. For illustrative purposes, an example in which the application is an automobile racing game application is used, and the virtual vehicle may be a racing automobile.

The virtual world is a three-dimensional virtual world constructed based on a three-dimensional virtual engine. The three-dimensional virtual world is provided with an environment constructed for the virtual vehicle to travel. The environment includes, for example, at least one of wildernesses, highways, tracks, and city streets.

A user interface is generated on the application and includes a traveling picture in which the virtual world is observed from a first perspective (e.g., a perspective of a driver or an interior perspective of a vehicle) or a third perspective of the virtual vehicle (e.g., a rear perspective of a vehicle or a far perspective), and a target interaction control overlaying the user interface. The target interaction control is a control or a set of controls configured to trigger a drift state of the virtual vehicle.

Operation S102. Control, according to the operation start event, the virtual vehicle to enter a drift state in the virtual world.

In some embodiments, the operation start event is triggered by a user operation on the target interaction control. Optionally, the target interaction control includes a direction control and a drift control displayed on a touch display screen. Alternatively, the target interaction control is a control corresponding to several physical modules on a racing automobile driving analog peripheral.

In some embodiments, the operation start event is triggered by a touch operation on the touch display screen, or may be triggered by a physical operation of controlling an external input device, for example, a physical operation of controlling a mouse, a VR handle, or the like.

In some embodiments, the user operation includes a tap operation, a combo operation, a long press operation, a slide operation, or the like. The type of the touch operation is not limited in this embodiment.

For example, the operation start event is generated in a case that a touch operation of simultaneously pressing a left direction key and a drift control starts to be performed by a user or is generated in a case that a touch operation of simultaneously pressing a right direction key and the drift control starts to be performed by the user.

The drift state refers to a movement state in which a vehicle body slides through a turn in a case that a relatively large angle is generated between a vehicle head direction and a traveling direction. The vehicle head direction refers to a direction directed to the front of the vehicle head. The traveling direction refers to a direction corresponding to a speed of the virtual vehicle during traveling, or an actual movement direction of the virtual vehicle in the environment provided in the application.

Operation S103. Control, in a case that an angle between a vehicle head direction and a traveling direction is greater than or equal to a first threshold after an operation end event corresponding to the target interaction control is received, the virtual vehicle to remain in the drift state.

In some embodiments, the terminal needs to monitor the angle between the vehicle head direction and the traveling direction of the virtual vehicle. Schematically, the monitoring includes, but is not limited to, at least one of the following four manners.

1. The angle between the vehicle head direction and the traveling direction of the virtual vehicle is monitored in real time in a case that the virtual vehicle is in the drift state.

2. After receiving the operation end event corresponding to the target interaction control, the terminal monitors the angle between the vehicle head direction and the traveling direction of the virtual vehicle in real time. The operation end event is triggered when the user operation on the target interaction control starts to disappear, for example, the operation end event is an event generated when a touch for a touch operation of simultaneously pressing the direction key and the drift control is canceled.

3. The terminal monitors the angle between the vehicle head direction and the traveling direction of the virtual vehicle at predetermined time intervals.

4. The terminal monitors the angle between the vehicle head direction and the traveling direction of the virtual vehicle upon receiving a direction control operation.

In a case that the angle between the vehicle head direction and the traveling direction is greater than or equal to the first threshold after the operation end event corresponding to the target interaction control is received, the terminal controls the virtual vehicle to remain in the drift state. “Remaining in the drift state” refers to a situation that, in a process in which the virtual vehicle is in the drift state, even if the user stops performing a drift trigger operation, provided that the angle between the vehicle head direction and the traveling direction remains to be greater than or equal to the first threshold, the terminal automatically controls the virtual vehicle to remain in the drift state (in other words, to continue the drift state and keep the drift state not being interrupted).

As shown in FIG. 2, the terminal displays a user interface 20 of the automobile racing application. The user interface 20 includes a left direction key 21, a right direction key 22, a drift button 23, and a virtual vehicle 24. The left direction key 21 is a control used for controlling the virtual vehicle 24 to move to a left side. The right direction key 22 is a control used for controlling the virtual vehicle 24 to move to a right side. The drift button 23 is a control used for triggering the virtual vehicle 24 to enter a drift state.

When the virtual vehicle 24 is driving in a curve, the user simultaneously presses the right direction key 22 and the drift button 23 as a drift trigger operation (the black fill color in the figure represents that the control is pressed). After receiving the drift trigger operation, the terminal controls the virtual vehicle 24 to enter a drift state.

After the user cancels pressing the right direction key 22 and the drift button 23 (the white fill color in the figure represents that the control is not pressed), if the terminal detects that the drift trigger operation is over, and that an angle α between a vehicle head direction and a traveling direction of the virtual vehicle 24 is greater than or equal to a threshold, then the terminal controls the virtual vehicle 24 to remain in the drift state.

Thus, according to the method provided in this embodiment, after the operation end event corresponding to the target interaction control is received, in a case that the angle between the vehicle head direction and the traveling direction is greater than or equal to the first threshold, the virtual vehicle is controlled to remain in the drift state. In this way, in the process of controlling the virtual vehicle to remain in the drift state, the user may only control the angle between the vehicle head direction and the traveling direction and does not need to simultaneously press a direction key and a drift control. Therefore, the user may only need to press the direction key to control the vehicle head direction to remain in the drift state, thereby reducing the difficulty of operation, and improving the convenience of man-machine interactions in some scenarios that are not suitable for long-term operation performed by using hands.

FIG. 3 is a flowchart of a drift method for a virtual vehicle in a virtual world according to another example embodiment of the disclosure. This embodiment is described by using an example in which the method is applicable to a terminal running an application. The application is a program allowing a virtual vehicle to enter a drift state in a traveling process of the virtual vehicle. The application is configured to perform the method including the following operations S301-S310.

Operation S301. Start an application.

There are various applications installed on a terminal. Start icons of the applications may be displayed on a desktop of the terminal.

A user may click/tap a start icon of an application. The terminal starts the application after the start icon is triggered. The application is an application provided with a virtual environment and a virtual vehicle located in the virtual environment. The application further allows the virtual vehicle to enter a drift state during traveling.

Operation S302. Display a user interface of the application, the user interface including a traveling picture of a virtual vehicle traveling in a virtual world.

The terminal runs the application and displays a user interface of the application. The user interface includes a traveling picture of a virtual vehicle traveling in a virtual world. The traveling picture displays a picture in which the virtual environment is observed from a first perspective or a third perspective of the virtual vehicle. The first perspective is also referred to as a perspective of a driver or an interior perspective of a vehicle, and the third perspective is also referred to as a rear perspective of a vehicle or a far perspective.

For example, when the virtual world is a three-dimensional virtual world, the first perspective may be implemented by using a first camera disposed at a position of a driver, and the third perspective may be implemented by using a second camera disposed at the rear of the virtual vehicle. The first perspective and the third perspective move as the virtual vehicle moves. In this embodiment, the traveling picture is described by using an example from the third perspective, and this is not limited herein.

In some embodiments, various types of controls overlay the traveling picture on the user interface. The control includes at least a direction key and a drift control. The direction key is a control used for controlling a movement direction of the virtual vehicle. The direction key includes at least one of a front direction key, a left direction key, a back direction key, and a right direction key. The drift control is a control used for controlling the virtual vehicle to trigger and/or remain in a drift state. When the direction key (e.g., any one of the front direction key, the left direction key, the back direction key, and the right direction key) and the drift control are simultaneously pressed, the virtual vehicle is controlled to enter the drift state. When the direction key and the drift control are continuously pressed, the virtual vehicle remains in the drift state during the continuous pressing.

This embodiment is described by using an example in which the target interaction control includes the direction key and the drift control.

In some embodiments, the control further includes, for example, at least one of a ranking display control, a speed information control, a thumbnail map control, a brake control, a jet control, and a nitrogen acceleration control. The ranking display control is a control used for displaying a racing automobile ranking of the current virtual vehicle among all virtual vehicles. The speed information control is a control used for displaying at least one piece of time information in individual record time, single-round racing time, and total racing time of this round. The thumbnail map control is a control used for displaying an entire track map (and a real-time position at which the current virtual vehicle is located on the track map) from a top view by using a preset scaling. The brake control is a control used for controlling the virtual vehicle to decelerate. The jet control is a control used for controlling the virtual vehicle to explosively accelerate in a relatively short first time period. A duration of the first time period may be a fixed duration. The nitrogen acceleration control is a control used for controlling the virtual vehicle to explosively accelerate in a relatively long second time period. A duration of the second time period may be dynamically determined according to a nitrogen attribute value.

In some embodiments, the jet control and the nitrogen acceleration control are both rewarded prop controls, which may be triggered and used only after the virtual vehicle meets a preset condition during traveling and obtains rewarded props. Otherwise, the jet control and the nitrogen acceleration control are displayed in an deactivated state and cannot be used. Schematically, the nitrogen acceleration control is a prop control that only may be triggered and used when an available nitrogen value accumulates to a threshold.

Operation S303. Receive an operation start event corresponding to a target interaction control in a process in which the virtual vehicle in the virtual world is in a normal traveling state.

The user controls the virtual vehicle to travel in the environment provided in the virtual world. During traveling, the user may use the direction key to control the traveling direction of the virtual vehicle.

As shown in FIG. 4, when the virtual vehicle is traveling in the virtual world, the virtual vehicle is affected by a normal traveling traction F1 and a resistance f. The normal traveling traction F1 refers to a traction directed to the front of the vehicle head, and the resistance f includes at least one of a friction from the ground and a wind resistance. The normal traveling traction F1 is greater than or equal to the resistance f.

In a process in which the virtual vehicle travels in the normal traveling state, the user may further trigger a drift trigger operation on the target interaction control. In some embodiments, the drift trigger operation includes a trigger operation with respect to the drift control. Alternatively, the drift trigger operation includes a trigger operation with respect to the direction control and the drift control. Alternatively, the drift trigger operation includes a trigger operation with respect to a driving analog peripheral.

In some embodiments, the drift trigger operation may be an operation triggered through a touch display screen, or may be an operation triggered by controlling an external input device, for example, an operation triggered by controlling a mouse, a VR handle, a driving analog peripheral, or the like. The driving analog peripheral includes at least one of a steering wheel, a gear lever, an accelerator, and a brake.

In some embodiments, the drift trigger operation may be a tap operation, a combo operation, a long press operation, a slide operation, or the like. The type of the drift trigger operation is not limited in this embodiment.

For example, the drift trigger operation is an operation of simultaneously pressing the left direction key and the drift control, or an operation of simultaneously pressing the right direction key and the drift control.

By using an example in which the drift trigger operation is an operation of simultaneously pressing a direction key and a drift control displayed on a touch screen, when the foregoing touch screen detects a user touch, a touch start event is generated in an operating system of the terminal. The touch start event is the operation start event.

Schematically, a touch event in the operating system of the terminal is triggered when the user puts a finger on the screen, slides the finger on the screen, and/or removes the finger from the screen. There may be the following several types of touch events.

Touchstart event (touch start event): this event is triggered when a finger starts to touch the screen. Even if one finger has been put on the screen, the event may still be triggered when another finger touches the screen.

Touchmove event (touch move event): this event is continuously triggered when a finger slides on the touch screen. During the occurrence of this event, rolling may be prevented by invoking a preventDefault( ) event.

Touchend event (touch end event): this event is triggered when a finger is removed from the touch screen.

An application in the terminal may determine the touch start event obtained at the foregoing program level as the operation start event corresponding to the target interaction control.

Operation S304. Control, according to the operation start event, the virtual vehicle to enter a drift state in the virtual world.

The drift state refers to a movement state in which a vehicle body slides through a turn in a case that a relatively large angle is generated between a vehicle head direction and a traveling direction. The vehicle head direction is directed to the front of the vehicle head of the virtual vehicle. The traveling direction is a direction in which the virtual vehicle moves in the virtual world.

Operation S305. Monitor an angle between a vehicle head direction and a traveling direction of the virtual vehicle.

In some embodiments, the terminal monitors the angle between the vehicle head direction and the traveling direction of the virtual vehicle, and the monitoring includes, but is not limited to, at least one of the following four manners.

1. The angle between the vehicle head direction and the traveling direction of the virtual vehicle is monitored in real time in a case that the virtual vehicle is in the drift state.

2. After receiving the operation end event corresponding to the target interaction control, the terminal monitors the angle between the vehicle head direction and the traveling direction of the virtual vehicle in real time. The operation end event is triggered when the user operation on the target interaction control starts to disappear, for example, the operation end event is an event generated when a touch for a touch operation of simultaneously pressing the direction key and the drift control is canceled.

3. The terminal monitors the angle between the vehicle head direction and the traveling direction of the virtual vehicle at predetermined time intervals.

4. The terminal monitors the angle between the vehicle head direction and the traveling direction of the virtual vehicle upon receiving a direction control operation.

In this embodiment, when the user stops touching the target interaction control (for example, the user lifts the finger from the direction key and the drift control), the operating system of the terminal generates the touchend event corresponding to the target interaction control, and the application in the terminal determines the touchend event as an operation end event. After the operation end event corresponding to the target interaction control is received, the terminal monitors the angle between the vehicle head direction and the traveling direction of the virtual vehicle.

In some embodiments, in the process of monitoring the angle, the terminal receives a direction control operation performed by the user, changes the vehicle head direction of the virtual vehicle according to the direction control operation, and determines an angle between the changed vehicle head direction and the traveling direction. The direction control operation may be an operation performed on the direction key, or may be an operation performed on a steering wheel.

For example, the direction control operation may be an operation of pressing the left direction key or an operation of pressing the right direction key.

After determining the angle between the vehicle head direction and the traveling direction of the virtual vehicle, the terminal further determines a magnitude relationship between the angle and a first threshold and a magnitude relationship between the angle and a second threshold, the first threshold being greater than the second threshold. Schematically, the first threshold is 45 degrees, and the second threshold is 10 degrees.

When the angle is greater than or equal to the first threshold, operation S306 is performed. When the angle is less than the first threshold and is greater than or equal to the second threshold, operation S313 is performed. When the angle is less than the second threshold, operation S311 is performed.

After the drift trigger operation is over, the vehicle head direction or the traveling direction of the virtual vehicle is affected by a plurality of factors such as a traction direction, the direction control operation, and a resistance and thus is changed. Further, because the user may perform a plurality of times of direction control operations, this operation may be correspondingly performed for a plurality of times.

Operation S306. Increase a dynamic drift-holding traction on the virtual vehicle along the vehicle head direction in a case that the angle between the vehicle head direction and the traveling direction is greater than or equal to the first threshold after an operation end event corresponding to the target interaction control is received, the dynamic drift-holding traction being used for controlling the virtual vehicle to remain in the drift state.

After the drift trigger operation triggered by the user on the target interaction control is over, if the terminal determines that the angle between the vehicle head direction and the traveling direction of the virtual vehicle is greater than the first threshold, the terminal increases a dynamic drift-holding traction on the virtual vehicle along the vehicle head direction, the dynamic drift-holding traction being used for controlling the virtual vehicle to remain in the drift state.

In some embodiments, the “remaining in the drift state” may be referred to as a drift-holding state.

As shown in FIG. 5, a direction of a dynamic drift-holding traction F2 of the virtual vehicle is directed to the front of the vehicle head. The virtual vehicle in the drift state moves according to a speed V along the traveling direction. The virtual vehicle is also affected by a friction f reverse to the speed V. A component F21 of the dynamic drift-holding traction F2 in the traveling direction is greater than or equal to the friction f, so that the virtual vehicle remains in the drift state. In this case, another traction component F22 of the dynamic drift-holding traction F2 changes the vehicle head direction, and the direction control operation performed by the user is needed to control the vehicle head direction of the virtual vehicle. Optionally, in a normal traveling state, the friction f is in a positive correlation with a speed of the virtual vehicle.

In some embodiments, an additional returnability is further added in the application. The returnability is used for guiding, in a case that no control signal exists, the virtual vehicle to automatically return to a vehicle head direction coinciding with the traveling direction during the drift.

In some embodiments, a traction component of the dynamic drift-holding traction in the traveling direction is greater than or equal to a resistance.

In some embodiments, a magnitude of the dynamic drift-holding traction is in a positive correlation with the speed of the virtual vehicle. Alternatively, in a preset speed range, a magnitude of the dynamic drift-holding traction is in a positive correlation with the speed of the virtual vehicle. After the preset speed range is exceeded, the magnitude of the dynamic drift-holding traction may remain unchanged.

In a possible implementation, the resistance received by the virtual vehicle is a ground friction. The ground friction is in a positive correlation with the speed of the virtual vehicle in the preset speed range, and a direction of the ground friction is reverse to the traveling direction. A friction component of the dynamic drift-holding traction received by the virtual vehicle in the traveling direction remains the same as the ground friction. Alternatively, the friction component is slightly greater than the ground friction but the friction component has a magnitude such that the virtual vehicle remains in the drift state.

Operation S307. Change a ground friction of the virtual vehicle from a first friction value to a second friction value in a case that the angle between the vehicle head direction and the traveling direction is greater than the first threshold after the operation end event corresponding to the target interaction control is received, the first friction value being greater than the second friction value.

In some embodiments, the first friction value is determined according to the speed of the virtual vehicle in real time. In a preset speed range, the speed of the virtual vehicle is in a positive correlation with the ground friction.

In some embodiments, the second friction value is a relatively small preset empirical value. When the application reduces the ground friction of the virtual vehicle in the process of holding the virtual vehicle in the drift state, the decay of the speed of the virtual vehicle caused by the ground friction may be reduced, so that the virtual vehicle is easier to remain in the drift state.

When there are a plurality of virtual vehicles in the virtual world, ground frictions of the virtual vehicles may be set independently of each other, depending on a current speed and a traveling state of the virtual vehicle.

Operation S308. Continuously increase a nitrogen attribute value of the virtual vehicle during the drift state.

In the process in which the virtual vehicle enters the drift state, the application continuously increases a nitrogen attribute value of a nitrogen acceleration control according to a duration of the drift state. The duration is in a positive correlation with the accumulated nitrogen attribute value. Herein, nitrogen and nitrogen attribute value are described as examples of an element used for accelerating the virtual vehicle in the application, but the disclosure is not limited thereto and includes any other elements that may indicate being usable for accelerating the virtual vehicle in the application and may be displayed in the user interface to be triggered by the user to accelerate the virtual vehicle.

Operation S309. Activate a nitrogen acceleration control of the virtual vehicle to an available state in a case that the nitrogen attribute value reaches a trigger threshold.

The nitrogen acceleration control corresponds to a trigger threshold. In a case that the nitrogen attribute value does not accumulate to the trigger threshold, the nitrogen acceleration control is in an unavailable state. An available state (or a deactivated state) is a state in which the nitrogen acceleration control is displayed on the user interface but cannot be triggered or a state not displayed on the user interface. In a case that the nitrogen attribute value accumulates to the trigger threshold, the nitrogen acceleration control is activated to an available state. The available state is a state in which the nitrogen acceleration control is displayed on the user interface and that may be triggered.

Operation S310. Control, in a case that a trigger signal with respect to the nitrogen acceleration control is received, the virtual vehicle to accelerate.

In some embodiments, the nitrogen acceleration control is a control displayed on the touch display screen. When the nitrogen acceleration control is in the available state, if the user presses the nitrogen acceleration control, the terminal receives a trigger signal with respect to the nitrogen acceleration control, and controls, according to the trigger signal, the virtual vehicle to accelerate.

The terminal may control, according to remaining available nitrogen in the nitrogen attribute value, the virtual vehicle to accelerate, that is, the acceleration process needs to constantly consume the nitrogen in the nitrogen attribute value. When the nitrogen in the nitrogen attribute value runs out, the terminal controls the virtual vehicle to exit from the acceleration state.

In some embodiments, if the virtual vehicle collides with another object in the acceleration process, the terminal also controls the virtual vehicle to exit from the acceleration state.

Operation S311. Control, in a case that the angle between the vehicle head direction and the traveling direction is less than the first threshold in the process of controlling the virtual vehicle to remain in the drift state, the virtual vehicle to restore the normal traveling state.

The terminal may switch a traction from the dynamic drift-holding traction to a normal traveling traction, the normal traveling traction being used for controlling the virtual vehicle to enter the normal traveling state.

Operation S312. Change the ground friction of the virtual vehicle from the second friction value to the first friction value in a case that the angle between the vehicle head direction and the traveling direction is less than the first threshold in the process of controlling the virtual vehicle to remain in the drift state.

In this case, the application further changes the ground friction of the virtual vehicle from the second friction value to the first friction value.

In some embodiments, the first friction value is determined according to the speed of the virtual vehicle in real time. In a preset speed range, the speed of the virtual vehicle is in a positive correlation with the ground friction.

In some embodiments, the second friction value is a relatively small preset empirical value.

Operation S313. Control, in a case that the angle between the vehicle head direction and the traveling direction is less than a second threshold after the operation end event corresponding to the target interaction control is received, the virtual vehicle to switch from the drift state to the normal traveling state after a target duration.

After the operation end event corresponding to the target interaction control is received, in a case that the angle between the vehicle head direction and the traveling direction is relatively small (for example, less than 10 degrees), the virtual vehicle enters another short drift state. The “short drift state” may be referred to as a point-drift state. The point-drift state is a state different from the drift-holding state. The application controls the virtual vehicle to switch from the drift state to the normal traveling state after a short target duration.

In some embodiments, the application calculates, according to the speed of the virtual vehicle and the ground friction, a decay duration during which the virtual vehicle decays from the drift state to the normal traveling state, controls, in a case that the decay duration is greater than a shortest drift duration, the virtual vehicle to decay from the drift state to the normal traveling state according to the decay duration, and controls, in a case that the decay duration is less than the shortest drift duration, the virtual vehicle to decay from the drift state to the normal traveling state according to the shortest drift duration.

In some embodiments, after the operation end event corresponding to the target interaction control is received, in a case that the angle between the vehicle head direction and the traveling direction is less than the second threshold, the application further changes the ground friction of the virtual vehicle from the second friction value to the first friction value, so that the virtual vehicle switches from the point-drift state to the normal traveling state.

In addition, the point-drift state is also a drift state. Therefore, the application further performs operation S308, that is, continuously increases a nitrogen attribute value of the virtual vehicle during the drift state (point-drift state). The point-drift state may help the user to quickly accumulate a few nitrogen attribute values. When the nitrogen attribute value accumulated in a drift-holding manner or an ordinary drift manner is to reach the trigger threshold, the user may accumulate the remaining nitrogen value by using the point-drift state.

Thus, according to the method provided in this embodiment, after the operation end event corresponding to the target interaction control is received, in a case that the angle between the vehicle head direction and the traveling direction is greater than the first threshold, the virtual vehicle is controlled to remain in the drift state. In this way, in the process of controlling the virtual vehicle to remain in the drift state, the user may only control the angle between the vehicle head direction and the traveling direction and does not need to simultaneously press a direction key and a drift control. Therefore, the user may only need to press the direction key to control the vehicle head direction, thereby reducing the difficulty of operation to remain in the drift state, and improving the convenience of man-machine interactions in some scenarios that are not suitable for long-term operation performed by using hands.

According to the method provided in this embodiment, after the operation end event corresponding to the target interaction control is received, at each time the direction control operation of the user is received, it is further determined whether the angle between the vehicle head direction and the traveling direction of the virtual vehicle is greater than a threshold. In a case that the angle between the vehicle head direction and the traveling direction of the virtual vehicle is greater than the first threshold, the virtual vehicle remains in the drift state, and the nitrogen attribute value of the nitrogen acceleration control is accumulated according to the duration in which the virtual vehicle is in the drift state (drift holding). In a relatively concise man-machine interaction manner, the user may quickly accumulate an available nitrogen value, to obtain more nitrogen acceleration controls of a rewarding property.

According to the method provided in this embodiment, after the operation end event corresponding to the target interaction control is received, in a case that the angle between the vehicle head direction and the traveling direction of the virtual vehicle is less than the second threshold, the virtual vehicle enters in the point-drift state, and the nitrogen attribute value of the nitrogen acceleration control is accumulated according to the duration in which the virtual vehicle is in the drift state (point drift). In a short man-machine interaction manner, the user may quickly accumulate a few available nitrogen values, and do not need to greatly change the traveling direction of the virtual vehicle, so that when the nitrogen attribute value accumulated in the drift-holding state or the ordinary drift state is to reach the threshold, the user may obtain the nitrogen acceleration control of a rewarding property more quickly by using the point-drift state.

FIG. 6 is a flowchart of a drift method for a virtual vehicle in a virtual world according to another example embodiment of the disclosure. In an example, the drift method in this embodiment include operations S601-S607

S601. The user opens the application and starts an automobile racing game.

S602. The user controls a vehicle to enter a drift by pressing buttons (e.g., the direction key and the drift key), and operation S604 is performed.

S604. When the virtual vehicle enters a drift, the application controls the racing automobile to remain in a drift state, and remaining in a drift state may be referred to as drift holding.

S603. The user releases the buttons (e.g., the direction key and the drift key) and cancels the drift trigger operation.

S605. If the user chooses to reset the vehicle head to a straight traveling direction, the user may trigger one or more of the following operations:

clicking/tapping the direction key, and rotating the vehicle head towards a direction away from to the drift direction (or toward the traveling direction);

continuously reducing an angle between the vehicle head direction and a movement direction of the vehicle; and

breaking from the drift state in a case that the angle is less than a certain degree.

S606. The application controls the racing automobile to end the drift, and when the vehicle head is successfully reset to the straight traveling direction during the drift, the vehicle enters the normal traveling state.

S607. If the user chooses not to reset the vehicle head to the straight traveling direction, the user may trigger one or more of the following operations:

setting an automatic returnability for the vehicle head when the vehicle enters a drift-holding state;

properly clicking/tapping the direction key, and rotating the vehicle head towards the same direction as the drift direction;

keeping the angle between the vehicle head direction and the movement direction of the vehicle approximately unchanged; and

remaining in a limitlessly drift-holding state.

The returnability is used for guiding, in a case that no control signal exists, the virtual vehicle to automatically return to a vehicle head direction coinciding with the traveling direction during the drift.

FIGS. 7 and 8 are schematic interface diagrams of a drift method for a virtual vehicle in a virtual world according to an example embodiment of the disclosure.

In some embodiments, as shown in FIG. 7, during the drift holding, the user interface may further be overlaid with and display a first character “drift holding” 71. According to another aspect, as shown in FIG. 8, during the drift holding, a tire trace 72 of the virtual vehicle on the track caused by the drift holding is shown longer.

Referring to FIG. 5, during the continuous drift of the racing automobile in this embodiment of the disclosure, in addition to an inertial speed V, there is also a relatively large ‘drift-holding’ power F2. The power and the friction f act jointly. In this case, an F/f power calculation changes dynamically, which results in a similar effect that the racing automobile is performing a uniform circular motion (a motion of a dynamic arc in the actual implementation). Theoretically, the “drift-holding” state of the racing automobile may be maintained indefinitely.

Schematically, FIG. 9 shows a calculation method of the dynamic drift traction F2 and the friction f according to an example embodiment of the disclosure. The dynamic drift traction F2 changes as a real-time speed of the racing automobile changes. A higher speed of the racing automobile indicates a larger dynamic drift traction F2. After the speed of the racing automobile reaches a certain degree, the dynamic drift traction F2 stops increasing. The traction f also changes as the real-time speed of the racing automobile changes, and a magnitude of the friction f is in direct proportion to the square of the real-time speed of the racing automobile.

During the drift holding, the user needs to control the vehicle head direction of the virtual racing automobile in real time, for example, control the angle between the vehicle head direction and the traveling direction to a range from 35 degrees to 45 degrees. A reason that the user needs to control the vehicle head direction is because the user needs to control the angle between the vehicle head direction and the traveling direction in real time not to be too small, otherwise the racing automobile exits the drift state. An operation basis of the drift holding is that the user controls the angle between the vehicle head direction and the traveling direction such that a joint force received by the racing automobile is maintained similar to a centripetal force, and the racing automobile performs a motion similar to a circular motion. In an actual implementation, the route of the racing automobile may not be a standard arc, but a non-standard arc that changes in real time. In this manner, the user may have better game experience using a track design. Different track arcs require players to control different drift angles.

In some embodiments, when the drift holding needs to end, the player needs to control the vehicle head to rotate so that the angle between the vehicle head direction and the traveling direction is 0 degrees (or a substantially small degree). In this way, the racing automobile is in the normal traveling state, and the dynamic drift traction F2 in FIG. 5 is switched to the normal traveling traction F1 in FIG. 4. F1 is a constant value, and the friction f still increases as the speed increases. A balance is finally achieved between the normal traveling traction f and the friction F1, and the racing automobile may perform a uniform linear motion in a line, which conforms to a power design principle of vehicles in the real world.

In an optional embodiment, after operation S603, if the user releases the buttons, and the angle between the vehicle head direction and the traveling direction of the virtual vehicle is within 10 degrees, the virtual vehicle does not enter the drift-holding state, but enters another short drift state referred to as the point-drift state. After maintaining the short drift state, the racing automobile switches from the drift state to the normal traveling state. In some embodiments, as shown in FIG. 10, during the point drift, the user interface may further be overlaid with and display a second character “point drift” 74.

In this way, in the process of controlling the virtual vehicle to remain in the drift state, the user may only control the angle between the vehicle head direction and the traveling direction and does not need to simultaneously press a direction key and a drift control.

Specifically, when the ambient light intensity is relatively high, the display luminance of the touch display screen 1205 is increased.
